An exemplary power conversion system comprises an MPPT unit, a DC bus, a power converter, and a converter controller. The MPPT unit receives a feedback current signal and a feedback voltage signal from a power source and generates an MPPT reference signal based at least in part on the feedback current and voltage signals. The DC bus receives DC power from the power source. The power converter converts the DC power on the DC bus to AC power. The converter controller receives the MPPT reference signal from the MPPT unit and an output power feedback signal measured at an output of the power converter; generates control signals for AC power regulation and maximum power extraction based at least in part on the MPPT reference signal and the output power feedback signal; and sends the control signals to the power converter.
